Subject: [PATCH v2 0/2] PCI: hv: Hyper-V vPCI for ARM64
Date: Fri, 8 Oct 2021 17:19:53 +0000	[thread overview]
Message-ID: <MW4PR21MB200217CCFBC351FD12D68DF0C0B29@MW4PR21MB2002.namprd21.prod.outlook.com> (raw)

Current Hyper-V vPCI code only compiles and works for x64. There are
some hardcoded assumptions about the architectural IRQ chip and other
arch defines.

This patch series adds support for Hyper-V vPCI for ARM64 by first
breaking the current hard coded dependency in the vPCI code and
making it arch neutral. That is in the first patch. The second
patch introduces a Hyper-V vPCI MSI IRQ chip for allocating SPI
vectors.

changes in v2:
 - Moved the irqchip implementation to drivers/pci as suggested
   by Marc Zyngier
 - Addressed Multi-MSI handling issues identified by Marc Zyngier
 - Addressed lock/synchronization primitive as suggested by Marc
   Zyngier
 - Addressed other code feedback from Marc Zyngier
